Speed Detection and Speed Limitation

Speed Agreement Function

There are eight different types of frequency detection methods available. The digital outputs M1 to M6 can be
set to this function and can be used to indicate a frequency detection or agreement to any external equipment.

Setting Precautions
With L4-01 an absolute speed agreement level is set, i.e. a speed agreement is detected in both directions
•
(Up and Down).
With L4-03 a signed speed agreement level is set, i.e. a speed agreement is detected only in the set direc-
•
tion (positive level → Up direction, negative level → Down direction).
